Ice Watch, a project by artist Olafur Eliasson and geologist Minik Rosing, in front of the Tate Modern in London, Dec. 12, 2018. Ice Watch is a display of 24 blocks of ice, fished out of the Nuup Kangerlua fjord in Greenland after becoming detached from the ice sheet. It's expected they will last between one week to 14 days before melting. It's hoped the project will help people better understand the reality of climate change. (Photo/Agencies)
